com'aor. DEVICE FOR RECEIPT PRINTING maonmE Application filed November6, 1929. Serial No. 405,264.

The present invention relates to apparatus for automatically controllingmachineswhich employ a paper feed roll and consists in the combinationsand arrangements of parts forth in the accompan ing claims.

The invention has 'fbr its purpose to provide a device for automaticallycontrolling the power source and operative mechanism of machinesdesigned for printing bills of sale, check or receipt printing, such ascash registers, fare registers, accounting and adding mechanisms, suchto be accomplished by means of an electriccircuit breaker and aninterlocking device that are caused to automatically function by theexhaust of the supply roll of paper.

I Systems now in use depend upon the opera tors ability to heed a signalthat is foretold by means of a change in the color of the paper at theextreme end of the paper roll before it is entirely exhausted. Undersuch a system if the paper supply is not replenished in due 7 time, theentire machine becomes clogged by the last of the receipt paperremaining in the machine when the supply is replenished.

By the use of my invention in connection with the machines enumeratedabove, such errors are avoided as well as any destruction to theprinting mechanism, because the operator is getting an unmistakablewarning by an inoperative machine thereby necessitating an immediatereloading of check paper.

The invention has for its further purpose to provide a mechanism of thischaracter which is constructed as a unit or device to the end that thesame may be readily applied to any cash register or adding or othermachine now in use without requiring rearrangement or constructionthereof; and wherein the normal operation and function of the machineare in no way interfered with.

Further advantages and objects of the invention are:

1. To eliminate all operations of the machine without issuing a receipt.

2. To protect the mechanism against illegible printing due to continuousinking of parts.

taken on the line 6-6 of Figure 2, and

3. To protect themechanism against severe strains and broken part-s duetopaper becoming clogged in machine. s

1. To eliminate burning of fuses on power lines.

5. To render machine operative by manual control for reloading of paperonly; inoperative by electric power.

6. To eliminate the extra paper from collecting in machine andobliterating the print on tally or the audit sheet.

Theinvention is shown by way of illustration in the accompanyingdrawings wherein Figure 1 is a side elevational view showing theapplication of the device. 7

Figure 6, a vertical detail sectional view motors and Figures 7 and 8are detail sectional views illustrating the locking device in operativeand in-operative positions respectively.

Referring to the construction in further detail and wherein likereference characters indicate corresponding parts the constructioncomprises a base member 9, an upright support 10, a frame or coversection 11, and the usual paper roll 12 whose spool o'r core V isjournaled on the axle or spindle 13, in the bracket arm-14 and frameportion 11, as shown. The construction above described is of the usualtype on cash'registers, accounting and adding machines, or check andreceipt printing mechanisms.

The invention herein disclosed comprise s a follower or'pla-te 15 thatextends for the width of the paper roll 12 and normally lies in contacttherewith as shown. The said 5- follower is pivotally mounted on thebracket arm 16 of the machine frame portion 11, and

a spring 17 normally holds the follower plate 15 under suflicientfrictional "contact with the paper roll 12, and also actsto op- .21

erate the controlling device when the paper roll has reached itsexhausted position as indicated in Figure 4.

The control device per se consists of a depending arm 18 fulcrumed onthe bracket arm 16 and carrying on its free end a shoe or yoke member 19having two laterally and oppositely projecting portions 20, and 2i whichfunction respectively to break the current and throw the machine lockingdevice. The shoe member 19 is of yoke-like design and is adapted to havelimited adjustment on its supporting arm 18 by the screw 22. (See Figurel.)

The current breaking member 20 is adapted to engage with the movablecontact 23 of the switch (2324) and therebyinterrupt the normal electriccircuit for controlling and actuating the machine. It is furtherproposed that this interruption or breaking of the currentwill put outthe usual lamps with which machines of this character are usuallyequipped for visible signaling purposes.

The member 21 of the shoe is adapted to engage with the projection 25 ofthe bar 26 that is slidably mounted on the frame portion 27 by the twostuds 28, as shown in Figures 5, 7, and 8.

The sliding bar 26 has an aperture 29 that normally lies in alinementwith the opening 30 that has movably mounted therein the control plunger31. A spring 32 acts to retract the sliding bar 26 when the same hasbeen displaced, and in its normal position theopening 29 of the barreceives the control plunger 31' as shown in Figure 7.

It will therefore be seen from the foregoing that when the paper rollhas been exhausted and the follower 15 has reached that position shownin Figure 6 the arm 18 carried by said follower will have reached theposition indicated in Figure 4 and thereby the switch (23 and 24) willbe open, and in like. manner the sliding bar 26 will be moved into itsiii-operative position. That is to say the condition of interlocking isproduced by the movement of the sliding bar to the position shown inFigure 8 which blocks or stops the forward movement of the plunger 31.To restore the machine to position for operation it is necessary only toreplace the exhausted roll of paper and raise the follower which carriesthe arm 18 when the contact is restored to normal and the bar 26 returnsto position under tension of spring 32. The hole 29 of the bar is thenin alinement with the opening 30 and allows the plunger 31 to comethrough when the control keys are again depressed.

It will be understood that the invention as herein disclosed is notlimited to the details of construction shown and described as these. maybe varied without departing from the spirit of the invention as definedby the claims.

What is claimed as new is:

1. The combination with a machine including a reel, a shiftable plunger,and an electric circuit closer, of a. control apparatus 'thereforcomprising a locking bar for the plunger, a reel follower, an armcarried by the reel follower, and a device carried by the arm havingportions adapted to simultaneously engage with and break the circuitcloser and to shift the plunger locking bar, for thepurpose set forth.

2. The combination with a machine in: cluding a reel, a shiftableplunger, and an electric circuit closer, of a control apparatus thereforcomprising a. locking bar for the plunger, a reel follower, an armcarried by the reel follower, and a member mounted on the free end ofthe reel follower arm having projecting portions adapted tosimultaneously engage with and break the circuit closer and to shift theplunger locking bar, for the purpose set forth.

3. The combination with a machine including a reel, a shiftable plunger,and an electric circuit closer, of a control apparatus thereforcomprising a locking bar for the plunger, a reel follower, an armcarried by the reel follower, and a yoke member adjustably mounted onthe free end of the reel follower arm having oppositely )rojectingportions adapted to simultaneously engage with and break the circuitcloser and to shift the plunger locking bar, for the purpose set forth.

4;. The combination with a machine including a. reel, a. shiftableplunger and an electric circuit closer, of a control apparatus thereforcomprising a shiftable and spring tensioned locking bar for the plunger,a spring tensioned reel follower, an arm carried by the reel follower, ayoke member ad,- justably mounted on the free end of the reel followerarm having oppositely projecting portions adapted to simultaneouslyengage with and break the circuit closer and to shift the plungerlocking bar for the purpose set forth.

In witness whereof, I have hereunto set my hand and seal at Washington,Jistrict of Columbia, this twenty-fifth day of October, A. D. nineteenhundred and twenty-nine.
